“Furthermore, this Paul said strongly that "the kingdom of God is not a matter of eating and drinking"—or abstinence from wine or meat—"but of righteousness, peace and joy in the Holy Spirit." Which of them goes around like Elijah wearing a sheepskin and a leather belt? Which of them wears no shoes and nothing but a piece of sackcloth like Isaiah? Or with nothing on but a linen loincloth, like Jeremiah?”
“The blessed John disdained sheep's wool because it savored of luxury; he preferred camel's hair and clothed himself in it, giving us an example of simple, frugal living. Incidentally, he also ate only honey and locusts, food that is sweet and with a spiritual significance. So it was that he prepared the way of the Lord and kept it humble and chaste. He fled from the false pretenses of the city and led a peaceful life in the desert with God, away from all vanity, boasting and servitude. How could he possibly have worn a purple mantle? Elijah used a sheepskin for his garment and girded it tight with a belt made of leather. Isaiah, another historic prophet, went "naked and without sandals" and often put on sackcloth as a garment of humility. If you protest and make mention of Jeremiah, he wore only a loincloth made of linen.”
